These Parmesan scalloped potatoes are layered with a creamy garlic and herb sauce, baked until golden and bubbly, and topped with nutty Parmesan. A rich and comforting side dish perfect for any occasion.
2½–3 lbs russet or Yukon Gold potatoes, peeled and sliced ⅛” thick
2 tbsp butter
2–3 garlic cloves, minced
2 cups heavy cream or half-and-half
1 tsp salt
½ tsp black pepper
1 tsp fresh thyme (or ½ tsp dried)
Optional: pinch of nutmeg
1 cup freshly grated Parmesan cheese
Extra cheese or breadcrumbs for topping (optional)
Fresh parsley, for garnish
Preheat oven to 375°F. Butter a 9×13″ baking dish.
In a saucepan, melt butter. Sauté garlic until fragrant. Add cream, salt, pepper, thyme, and nutmeg. Simmer 3–4 mins.
Stir in Parmesan. Remove from heat.
Layer half the potatoes in the baking dish. Pour over half the cream sauce. Repeat with remaining potatoes and sauce.
Cover with foil and bake 35–40 mins. Uncover and bake 20–25 mins more, until golden and bubbly.
Rest 10–15 mins before serving. Garnish with parsley.
